IMPROVEMENT IN FEED-STEAMERS.A

Specification forming part of Letters Patent No. 209,063, dated October15, 1878 application filed March 23, 1878.

To all 'whom it may concern:

Beit known that we,DAN1EL MACHAMER and JOHN MCCULLOOH, of Lena, in thecounty of Stephenson and State of Illinois, have invented a new andvaluable Improvement in Feed-Steamers; and we do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon.

Figure l of the drawings is arepresentation of longitudinal verticalsection of our foodsteamer. Fig. 2 is a plan view. Fig; 3 is a sideview, and Fig. 4 is a plan view of the vat.

The nature of our invention consists in certain improvements in aportable furnace and feed-steamer, as will be hereinafter more fully setforth, and pointed out in the claim.

rlhe annexed drawings, to which reference is made, fully illustrate ourinvention.

Our feed-steamer furnace is composed of a continuous bottom plate, A,bent in the form substantially as shown, a front, B, havingsuitabledoors for the lire-box and ash-pit, and sides O. These sides aremade in sections, joined together by means of outside coveringstrips, aa, riveted to them. Around the upper edges is a flanged rim, D, alsovmade in sections and fastened to the furnace, the whole being firmlyunited by cross-rods b b at top and bottom, which rods are provided withnuts d both inside and outside of the furnace.

E is the grate upon which the fire is built. About midway in the furnaceisa valve, F, extending across the same, and hinged at its lower end bya rod, c, which has a lever, G, on one end outside the furnace, as shownin Fig. 3 of the drawings. This lever is formed with ratchet-teeth x fora pawl, f, to take into, for the purposes of elevating or raising thehinged plate H, and retaining the same at any height.

The upper end of the valve F passes under the front end of a plate, H,which is hinged at the rear end of the furnace, and has its front endbent downward over the valve, as shown in Fig. 1 of the drawings.

By raising the valve F the plate H is also raised, whereby the heat andflame are caused J as shown in Fig. 4, which run longitudinally in thesame. At the front end these pipes unite in a single pipe, J', whichpasses down through ,and opens through the bottom of the vat into thefn'echamber. At the rear end these pipes also unite and communicate witha smoke-pipe, K.

It will be observed that when the valve is raised the heat and productsof combustion will pass up the pipe J f, and as they enter the pipes Jthey are divided, a portion passing' to the right and the other portionto the left, thereby distributing the heat uniformly throughout thepipes, and heating the water in the vat more readily than can be done byordinary means. The heat passes not only under the vat, but also throughthese pipes, thereby giving double heat.

On top of the pipes in the vat is fitted a plate, L, having one or more'short tubes, 7L, through it. These tubes are perforated above theplate, and on their upper ends are attached caps M. This device allowsthe steam to escape from the feed, while the caps prevent the holes fromclogging.

We are aware that a steam cooking apparatus with a ,flue and avalve tocause the heat and products of combustion to pass either under thebottom ofthe pan or through a fine in the pan have heretofore been used.

What we claim as new, and desire to secure by Letters Patent, isy Thepivoted or hinged valve F and hinged plate H, with means for holding thesame at A different heights, in combination with pipes J J and vat I,substantially as and for the purposes set forth.

In testimony that we claim the above we have hereunto subscribed ournames in the presence of two witnesses.
